Aspects Of The Nesting Ecology Of Least Terns And Piping Plovers In Central Nebraska, Craig A. Faanes

Papers in Ornithology

Breeding habitat of the least tern is made up primarily of coastal beaches and inland river sandbars. Populations of the interior (Sterna antillarum athalassos) and east coast (S. a. antillarum) subspecies are now declining (Marshall et al. 1975, Duffy 1977, Jernigan et al. 1978) and the western subspecies (S. a. browni) is endangered (Wilbur 1974). Although coastal populations have received considerable attention (Wolk 1974, Atwood et al. 1977, Blodgett 1978), little research has been conducted on the interior race (Hardy 1957, Downing 1975).

The piping plover inhabits river sandbars and sand beaches and, like …

Treatment Of Paget's Bone Disease With The Bisphosphonate Apd, Carlos A. Mautalen

Henry Ford Hospital Medical Journal

Thirty-two patients with Paget's bone disease have been treated with the bisphosphonate APD. Nineteen had previously received treatment for Paget's disease with EHDP alone or in combination with calcitonin; 13 had not previously received treatment for Paget's disease. APD was given in a mean dose of 6.8 mg/kg of body weight during a period of 6 to 12 months. Bone pain disappeared or diminished in 91% of the patients. A very significant diminution of the biochemical indices of bone turnover was observed in all patients, but the response occurred faster in patients who had not previously received treatment for Paget's …

The Effects Of Photoperiod On The Prolactin Cells Of Notropis Cornutus (Mitchell), Matthew Kevin Hettinger

Masters Theses

Three groups of the common shiner (Notropis cornutus, Mitchell) were adapted to three different photoperiods. These photoperiods were 16L:8D (summer), 12L:12D (controls), and 8L:16D (winter). The prolactin cells were studied histologically and morphologically with respect to staining characteristics, cell and nuclear morphology, nuclear size, and cellular density. The prolactin cells of those fish under the long photoperiod exhibited greater cellular activity than the controls as evidenced by an increase in nuclear size, cellular density, and by becoming more circular. The prolactin cells of those fish under the short photoperiod exhibited the same characteristics as those in the long photoperiod. The …

A Study Of The Environmental Aspects Of Schistosomiasis In Libya, Abubaker I. Swehli

Dissertations

Schistosomiasis is a serious disease in humans. Two species of schistosome, Schistosoma mansoni and Schistosoma haematobium, organisms that cause the disease, parasitize humans in Libya. Schistosomes require aquatic snails in their life cycle. The purpose of this study was to investigate the environmental and the host relationships of the disease in the three regions of Libya where the disease is found. These relationships include:

1) Analyses of the physical-chemical characteristics of the aquatic habitat.

2) Collection of snails to determine: a) the kind of snail species and th e ir abundance; and b) the cercarial infestation rates.

3) Infection rates …

The Effect Of Feeding, Bilateral Parotidectomy, And Pilocarpine Treatment On Parotid Hormone Secretion In The Pig, Jocelyn Celestin

Loma Linda University Electronic Theses, Dissertations & Projects

The effect of feeding, bilateral parotidectomy, pilocarpine treatment, visual and olfactory, and masticatory stimuli on parotid hormone (PH) secretion is reported. Feeding a regular chow was shown to be a potent stimulus for PH secretion. The parotid endocrine system is highly sensitive to the eating stimulus, since a period of feeding lasting 30 sec is enough to cause a significant increase in PH secretion. The parotid glands are the principal source of PH as shown by the marked decrease in basal PH titer, and a virtual absence of response of PH to feeding in parotidectomized pigs. Pilocarpine administration provoked profuse …

A Checklist Of Parasites Of California, Oregon, And Washington Marine And Estuarine Fishes, Milton S. Love, Mike Moser

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This report is a summary of the published records of parasites found from the marine and estuarine fishes of California, Oregon, and Washington. Coverage has not been limited to the western United States, but rather includes parasite reports from throughout each fish's range. Included is a host-parasite list and parasite-host cross index.

We have produced this survey because we felt there was a need for a single source which would list all the parasites infecting marine and estuarine fish from California, Oregon, and Washington. Pertinent sources are scattered over a number of journals, covering many years. Workers find it time …

Histopathology In Rat Temporal Bones Resulting From Excess Dietary Fluoride In Conjunction With Suspected Water Born Toxins, Donna Lee Healy

Masters Theses

The occurrence of perinatal deaths, bony extoses, and deafness in dog kennels in certain areas of Michigan led The Upjohn Company and Western Michigan University to suspect fluoride toxicity and/or water born toxins. The present project was designed to examine the ability of excess fluoride ingestion and/or the ability of suspected water born toxins to induce histopathology in Sprague-Dawley rats. An otopathological assessment of the rat temporal bones showed no otopathology nor any changes in cochlear dimensions, however, a quantitative assessment of osteoclastic density showed a large increase in the numbers of osteoclasts of spongy bone in the high fluoride …

Rearrangement Of The Keratin Cytoskeleton After Combined Treatment With Microtubule And Microfilament Inhibitors, Loren W. Knapp, W. Michael O'Guin, Roger H. Sawyer

Faculty Publications

In addition to containing microtubule and microfilament systems, vertebrate epithelial cells contain an elaborate keratin intermediate-filament cytoskeleton. Little is known about its structural organization or function. Using indirect immunofluorescence microscopy with an antikeratin antiserum probe, we found that destabilization of microtubules and microfilaments with cytostatic drugs induces significant alterations in the cytoskeletal organizationof keratin filaments in HeLa and fetal mouse epidermal cells. Keratin filament organizationwas observed to undergo a rapid (1-2 h) transition from a uniform distribution to an open lattice of keratin fibers stabilized by membrane-associated focal centers . Since addition of any one drug alone did not elicit …

The Effect Of Orally Administered Butylated Hydroxytoluene On Herpes Simplex Keratitis, Donald Carson

Masters Theses & Specialist Projects

Some studies have reported in vitro inactivation of membrane enveloped viruses by Butylated hydroxytoluene (BHT). This study investigates the effect of orally administered BHT on primary infections of Herpes simplex virus (HSV) using rabbit corneas as the assay system.

Assigned levels of BHT were incorporated into the diet of New Zealand White rabbits with HSV-1 McKrae strain on the corneal surface of the eyes. The degree of infection was measured by a subjective assay. Rabbits receiving BHT in their diet consistently experienced lower levels of infection. The interpretation of this data is that orally administered BHT can be an effective …

Germ Line-Specific Dna Sequences Are Present On All Five Micronuclear Chromosomes In Tetrahymena Thermophila, Kathleen M. Karrer

Biological Sciences Faculty Research and Publications

The development of the macronucleus from the zygotic micronucleus in the ciliated protozoan Tetrahymena spp. involves the elimination of specific DNA sequences (M. C. Yao and M. Gorovsky, Chromosoma 48:1-18 1974). The present study demonstrates that micronucleus-specific DNA is present on all five of the micronuclear chromosomes. Fragments of micronuclear DNA from Tetrahymena thermophila were cloned in the plasmid vector pBR322. A procedure was developed to examine the organization of the cloned sequences in micro- and macronuclear DNA without nick translating each individual probe. Twenty-three percent of randomly selected DNA sequences examined by this method were micronucleus (germ line) specific. …

Suppression Of Colorado Potato Beetle, Leptinotarsa Decemlineata (Say), (Coleoptera: Chrysomelidae) Populations With Antifeedant Fungicides, J. Daniel Hare, Patrick A. Logan, Robert Wright

Department of Entomology: Faculty Publications

Laboratory, small-field plot, and commercial-scale experiments were completed, using Connecticut, Rhode Island, and New York Colorado potato beetle, (CPB) Leptinotarsa decemlineata (Say), populations to determine if "antifeedant fungicides" might reduce the suitability of potato for CPB while simultaneously protecting potato from early and late blight. In the laboratory. fungicides formulated from triphenyltin hydroxide (TPTH) or Cu(OH), reduced CPB feeding 95 and 61%. In small-field plots, CPB larval densities were significantly reduced where TPTH and Cu(OH)₂ were used regularly. In commercial-scale experiments, L. decemlineata populations were significantly reduced and required fewer insecticide applications for acceptable control where TPTH was used …

The Distribution Of Phytoplankton In Frontal Regions Of The Lower Chesapeake Bay, Richard V. Lacouture

OES Theses and Dissertations

The spatial and temporal distribution of phytoplankton was measured in relation to frontal areas located in the entrance to the Chesapeake Bay. Phytoplankton biomass, taxonomy, and several physical parameters were measured on fifteen sampling cruises between September,1981 and February, 1983.

Several statistical tests revealed that phytoplankton biomass did not accumulate at the fronts and that generally the distribution of phytoplankton biomass was homogenous across the frontal region. The cell count data indicated that the community structure of the phytoplankton assemblage was usually very similar on both sides of the front. The data which was concerned with temporal variations in the …

The Effects Of Dominant Species Removal On Subtidal Community Development, H. Russell Barker Jr.

Biological Sciences Theses & Dissertations

Acrylic panels were used to follow the development of the fouling community at Channel Points, Lynnhaven Bay, Virginia, from April through October 1979. The roles of Membranipora tenuis, an encrusting ectoproct, and Molgula manhattensis, a solitary tunicate, were studied by removing each species from the developing community on a weekly basis.

Early colonization was dominated by Membranipora followed by Corophium spp. (Amphipoda), Polydora ligni (Polychaeta), and Balanus eberneus (Arthropoda). Molgula colonized the panels later in the study and became a dominant occupier of primary space by the end of the study.

The removal of Membranipora and Molgula …

High Resolution Two Dimensional Electrophoresis Of Soluble Proteins In Human Spermatozoa, Hsing-Ying Liu

Chemistry & Biochemistry Theses & Dissertations

The evaluation of human semen is very important for diagnosis of male infertility. Combined with the analysis of seminal plasma, a comprehensive biochemical screening of human spermatozoan proteins may be of assistance in providing qualitative and quantitative information to the physician to assist with evaluation.

In this study, human spermatozoa were ruptured by sonication. The soluble spermatozoan proteins were separated from the cellular debris by centrifugation and then analyzed in dissociated forms by two dimensional electrophoresis. The separated proteins were visualized by a silver stain method.

It has been shown that these combined techniques can resolve- four to five hundred …

The Effect Of Sea Nettle Abundance On The Food Chain Of The Lower Chesapeake Bay, Michael Glenn Kelly

OES Theses and Dissertations

The significance of sea nettle abundance on lower levels of the Chesapeake Bay food chain was examined in a field study and by the analysis of medusa gut contents. In the field study, the abundance of four levels of the food chain (Chlorophyll (a), copepods, the ctenophore Mnemiopsis leidyi, and the Schyphomedusa Chrysaora guinguecirrha) were monitored twice weekly at four stations from May 10 through September 30, 1982. The copepod standing stock declined sharply in late May when M. leidyi appeared, but rebounded a month later when C. guinguecirrha medusae reduced the ctenophore population. Despite the additional presence …

Adaptations Of Dolphin Vision To The Oceanic Environment, Andre Rivamonte

OES Theses and Dissertations

The objective of this study has been to develop an hypothesis explaining comparable aerial and underwater visual acuity of the bottlenose dolphin, Tursiops truncatus. This objective was accomplished by integrating the findings of other dolphin researchers working in the fields of comparative psychology, histology and ophthalmology. Their combined results enabled the formulation of a schematic dolphin eye. It is proposed that a dolphin lens, similar to the spherical lens of teleost fish with a rigid core of uniformly high refractive index and a margin of radially decreasing refractive index, could function as a bifocal lens and compensate for the eye's …

The Effects Of Dredged Materials On The Copeod, Acartia Tonsa, Renee Suzanne Crouch

Biological Sciences Theses & Dissertations

A study was conducted to determine the potential impact of open ocean disposal of sediments dredged from a highly industrialized seaport. Sediments from three potential dredge sites along the Southern Branch of the Elizabeth River, Hampton Roads, Virginia were evaluated for acute toxicity. The suspended particulate fractions of dredged materials were tested in a series of 96-hour, static bioassays using the calanoid copepod, Acartia tonsa Dana. Significant mortalities were observed for all three sites with the sediments from the most heavily industrialized site producing immediate and severe mortality. Analysis of results indicates that mortality was highly related to the volatile …
